编译你的程序

Makefile

通过在根目录中编写包含常用命令的./Makefile来帮助用户编译应用程序：

注意：下面的Makefile包含一些与Cosmos SDK和Tendermint的Makefiles相同的命令。

DEP := $(shell command -v dep 2> /dev/null)

get_tools:
ifndef DEP
    @echo "Installing dep"
    go get -u -v github.com/golang/dep/cmd/dep
else
    @echo "Dep is already installed..."
endif

get_vendor_deps:
    @echo "--> Generating vendor directory via dep ensure"
    @rm -rf .vendor-new
    @dep ensure -v -vendor-only

update_vendor_deps:
    @echo "--> Running dep ensure"
    @rm -rf .vendor-new
    @dep ensure -v -update

install:
    go install ./cmd/nsd
    go install ./cmd/nscli

Gopkg.toml

Golang有一些依赖管理工具。在本教程中，你将使用dep。dep使用仓库根目录中的Gopkg.toml文件来定义应用程序所需的依赖项。Cosmos SDK应用程序目前依赖于某些库的特定版本。以下列表包含所有必需的版本。首先使用下面的constraints和overrides项替换./Gopkg.toml文件的内容：

# Gopkg.toml example
#
# Refer to https://golang.github.io/dep/docs/Gopkg.toml.html
# for detailed Gopkg.toml documentation.
#
# required = ["github.com/user/thing/cmd/thing"]
# ignored = ["github.com/user/project/pkgX", "bitbucket.org/user/project/pkgA/pkgY"]
#
# [[constraint]]
#   name = "github.com/user/project"
#   version = "1.0.0"
#
# [[constraint]]
#   name = "github.com/user/project2"
#   branch = "dev"
#   source = "github.com/myfork/project2"
#
# [[override]]
#   name = "github.com/x/y"
#   version = "2.4.0"
#
# [prune]
#   non-go = false
#   go-tests = true
#   unused-packages = true

[[constraint]]
  name = "github.com/cosmos/cosmos-sdk"
  version = "v0.31.1"

[[override]]
  name = "github.com/golang/protobuf"
  version = "=1.1.0"

[[constraint]]
  name = "github.com/spf13/cobra"
  version = "~0.0.1"

[[constraint]]
  name = "github.com/spf13/viper"
  version = "~1.0.0"

[[override]]
  name = "github.com/tendermint/go-amino"
  version = "v0.14.1"

[[override]]
  name = "github.com/tendermint/iavl"
  version = "v0.12.0"

[[override]]
  name = "github.com/tendermint/tendermint"
  version = "v0.30.0-rc0"

[[override]]
  name = "golang.org/x/crypto"
  source = "https://github.com/tendermint/crypto"
  revision = "3764759f34a542a3aef74d6b02e35be7ab893bba"

[[override]]
  name = "github.com/otiai10/copy"
  revision = "7e9a647135a142c2669943d4a4d29be015ce9392"

[[override]]
  name = "github.com/btcsuite/btcd"
  revision = "ed77733ec07dfc8a513741138419b8d9d3de9d2d"

[prune]
  go-tests = true
  unused-packages = true

注意：如果你再你自己的仓库重头开始编写项目，请确定在运行dep ensure -v之前你已经导入路径github.com/cosmos/sdk-application-tutorial替换成你自己的整个仓库(可能是github.com/{.Username}/{.Project.Repo})。如果不这样做，则需要在再次运行dep ensure -v之前删除./vendor目录（rm -rf ./vendor）以及Gopkg.lock文件（rm Gopkg.lock）。

既然已经完成了这项管理工作，是时候安装dep以及项目依赖：

make get_tools
dep ensure -v

编译应用程序

# Update dependencies to match the constraints and overrides above
dep ensure -update -v

# Install the app into your $GOBIN
make install

# Now you should be able to run the following commands:
nsd help
nscli help
